Greatest Common Factor
We found the factors 424,655 . The biggest common factor number is the GCF number.
So the greatest common factor 424,655 is 1.
Lets's calculate LCM of 823,758
Given numbers has no common factors except 1. So, there LCM is their product i.e 623834
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/623834
Therefore, the GCF of Fractions 424/823,655/758 is 1/623834
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 823,758 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(823,758) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(823,758) x common factors =1 x 1 = 1
LCM(823,758) = ( 823 × 758 ) / 1
LCM(823,758) = 623834 / 1
LCM(823,758) = 623834
